Tribonema (tribe-owe-knee-ma) is a xanthophyte, a group of stramenopiles with chloroplasts. Xanthophytes may adopt a variety of body forms, and the normal form for this genus is the filament. Cell walls often built from H-shaped units, and these overlap in the middle of a cell. Stalked attached cells also occur, as is evident here. Plastids usually discoid, yellow green. Phase contrast

The oblique view exhibits short silicous spines, the so called occluded processes. Some chitinous spines protruding from the fultoportulae (also called strutted processes) along the dotted valve margin are also visible. Scale bar indicates 50 µm. The image was built up using several photomicrographic frames with manual stacking technique. Sample from North Sea near Heligoland (spring diatom bloom). Images were taken using Zeiss Universal with Olympus C7070 CCD camera.
